  • Double-rail cable window raiser systems Double-rail cable window raiser systems.
  • the problem to be solved is centered on achieving an increase in the number of life cycles of double-rail cable window raiser system.
  • the window raiser systems must withstand a certain number of life cycles. This number of cycles usually varies between 30,000 and 50,000.
  • U.S. Pat. No. 5,359,811 and U.S. Pat. No. 5,490,354 A window raiser system wherein different types of cable are used depending on the area where they are located is shown in these patents. Cables with high load capacities in the segments so requiring it are resorted to because they will have to withstand high stresses, and in the areas in which the stresses are lower, a type of cable with a lower load capacity is used. Thereby, the cable of the window raiser system is optimized by using high-strength cable segments (higher cost) in the areas of greater stressing.
  • EP0834634 a kinematic chain wherein two cable winding drums are used is protected in this patent; thus, the stresses withstood by one cable in a traditional configuration of the kinematic chain are distributed in two cables, whereby the working life of these cables is incremented.
  • a first aspect of the invention relates to a window raiser having:
  • a first redirecting means a second redirecting means, a third redirecting means, and a fourth redirecting means.
  • the flexible connecting means form a crossed, closed loop extending from the first displacement means around the first redirecting means and the second redirecting means to the second displacement means, and from the second displacement means around the third redirecting means and the fourth redirecting means back to the first displacement means.
  • Said flexible connecting means comprise:
  • the arrangement of the components of the window raiser is:
  • the first displacement means arranged between the fourth redirecting means and the first redirecting means along the path;
  • the first redirecting means arranged between the first displacement means and the driving means along the path;
  • the second redirecting means arranged between the driving means and the second displacement means along the path.
  • the first portion around the first redirecting means and the cable winding drum connected to the driving means, the second portion around the second redirecting means and the cable winding drum connected to the driving means are configured to rotate (a change of direction being understood as a rotation) in the same direction.
  • no alternate stressing occurs, that is, along the path of the first portion the flexible connecting means bend in the same direction in both the first cable redirecting member and the driving means, and along the path of the second portion the flexible connecting members bend in the same direction in both the second redirecting member and the driving members.
  • the first portion is configured to bend in a first direction in the first redirecting means and in the cable winding drum connected to the driving means;
  • the second portion is configured to bend in a second direction in the second redirecting means and in the cable winding drum connected to the driving means; the first direction coinciding with the second direction.
  • the window raiser of the invention has:
  • the first displacement means and the second displacement means are displaced between an upper position and a lower position
  • the second redirecting means is arranged in a position selected from upper front, lower front, upper rear, and lower rear.
  • there can also be a window raiser wherein the third portion around the third redirecting means and around the fourth redirecting means is configured to rotate in the direction of the first portion around the first redirecting means and the cable winding drum connected to the driving means, the second portion around the second redirecting means and the cable winding drum connected to the driving means.
  • the third portion is configured to bend in a third direction in the third redirecting means and the fourth redirecting means; the third direction coinciding with the first direction and the second direction.
  • the flexible connecting means, or cable bend in the same direction in both the third redirecting means, or pulley, and the fourth redirecting means.
  • the window raiser may further comprise:
  • the driving means to which the cable winding drum is connected are arranged in the intermediate area delimited by the path of the displacement means, that is, it is located in the intermediate area of the rails of the window raiser.
  • first sliding means, or first rail, and the second sliding means, or second rail may be made up of the same element; either a first front sliding means is further used as a rear sliding means or a second rear sliding means is further used as a front sliding means.
  • the portions of the flexible connecting means may be selected from, for example, cable, tape, belt, and combinations thereof.
  • the redirecting means may be selected from, for example, pulleys, clips, and combinations thereof.
  • the driving means may be selected from manual and electrical means.
  • the flexible connecting means are made up of a single member.
  • the flexible connecting means comprise:
  • FIG. 1 is a diagram showing the second redirecting means in a lower rear position.
  • FIG. 2 is a diagram showing the second redirecting means in an upper rear position.
  • FIG. 3 is a diagram showing the second redirecting means in a lower front position.
  • FIG. 4 is a diagram showing the second redirecting means in an upper front position.
  • FIGS. 5 and 6 are two diagrams showing window raisers where the flexible connecting means bend around the first, second, third, and fourth redirecting means in the same direction.
  • FIG. 7 is a diagram of a conventional kinematic chain.
  • FIGS. 8 and 9 are two diagrams wherein bending of a conventional kinematic chain and in any of the alternatives of the kinematic chain of the invention is observed.
  • the configuration of the kinematic chain of the window raiser is designed such that the cable or flexible connecting means 1 does not undergo an alternate stressing.
  • a first configuration which in turn comprises four alternatives, the exit of the cable or flexible connecting means 1 of one of the pulleys, or second redirecting means 200 , joining one of the carriages, or second displacement means 20 , with the cable winding drum connected to the driving means 2 , is changed.
  • this cable or flexible connecting means 1 undergoes alternate stressing, that is, the cable, along its path through the different lengths which make it up, alternatively bends in the members of the kinematic chain in which it changes its direction, thereby causing the premature wear of the cable and its subsequent rupture, limiting the number of life cycles thereof.
  • the cable or flexible connecting means 1 joining both carriages or first and second displacement means 10 , 20 is not subject to an alternate stressing because the distance between pulleys or redirecting means is greater than the stroke of the windowpane.
  • the exit of the cable is changed in the redirecting means corresponding to the portion in which an alternate stressing exists; thereby, the cable corresponding to this portion has its exit towards the outside of the area comprised between the two rails of the window raiser. An alternate stressing is thereby prevented along the path of this length of cable.
  • the length of the rail or sliding means 2000 in which the exit of the cable or flexible connecting means 1 joining a carriage or second displacement means 20 with the winding drum from the cable driving means 2 is changed can be lengthened so that no interferences occur between both elements.
  • This configuration is achieved by means of the use of just one rail reference: just one type of rail is used for both the front rail and the rear rail.
  • This configuration is specially advantageous in that is means saving one reference, without a specific type of rail being necessary depending on whether said rail is the front or rear one, entailing a cost reduction and a simplification of the window raiser assembly.
  • the working life of the cable and consequently that of the window raiser system are increased, achieving that the latter withstands a number of cycles far greater than conventional window raisers without incurring in an increase of the cost or complexity of the kinematic chain, as occurs with systems known in the state of the art.
  • a double-rail cable window raiser system is made up of the following elements:
  • Rails or sliding means 1000 , 2000 the profiles through which the carriages or displacement means 10 , 20 of the window raiser can slide. They can be made up of metal profiles manufactured by means of cold molding, usually by rolling or stamping. They can also be manufactured by means of other processes such as light alloy injection or plastic injection.
  • Carriages or displacement means 10 , 20 the connection members between the rails or sliding means 1000 , 2000 and the windowpane.
  • the carriages or displacement means 10 , 20 slide along the rails or sliding means 1000 , 2000 so as to cause the upward and downward movement of the windowpane.
  • the carriages or displacement means 10 , 20 are usually threaded in the rails or sliding means 1000 , 2000 and are joined to the windowpane for example by screw driving.
  • Driving cable or flexible connecting means 1 it is the traction member of the system transmitting the movement from the driving member or driving means 2 .
  • Said driving member or driving means 2 may be both a manual system: handle, and an electrical system: reduction motor.
  • Driving system or means 2 it can be manual by means of a handle which is mounted on the cable winding drum or electrical by means of the use of a reduction motor which is connected to the cable winding drum.
  • the drum to which the corresponding driving means is connected is made up of a grooved cylinder in which the cables are wound such that one of the cables, the one corresponding to a first portion, is wound in one direction and the one corresponding to a second portion is wound in the opposite direction.
  • Redirecting means 100 , 200 , 300 , 400 they are the elements in charge of redirecting the cable or flexible connecting means 1 . Typically, they are four made of plastic material and located at the ends of the rails or sliding means 1000 , 2000 . Hereafter, the term pulley will be used, but other elements performing the same redirecting function such as clips or the like may be used.
  • a kinematic chain wherein the cable is not subject to an alternate stressing in the cable redirecting and cable winding drum areas has been designed. Further, several elements comprising the window raiser system have been optimized (type of cable, use of greases inside the drives, . . . ).
